how to get data from body parser in array using node js? - node.js

Question

Here I'm having no_of_devices which has three fields 'macAddress', 'useWith' and 'type' in a row, the count of row depends upon the number of devices selected from select field, so I'm using body-parser and i want to get all the row data which has name generated using for loop so all the rows having macAddress will have name='macAdd0',name="macAdd1" etc same goes with 'type' and 'useWith' field.
HTML
<select id="noOfDevice" class="form-control" name="noOfDevice" onchange="getDeviceCount(this)">
<option selected value="0">Select</option>
<option value="1">01</option>
<option value="2">02</option>
<option value="3">03</option>
<option value="4">04</option>
<option value="5">05</option>
<option value="6">06</option>
<option value="7">07</option>
<option value="8">08</option>
<option value="9">09</option>
<option value="10">10</option>
</select>
Javascript
<script>
var macAdd;
var useWith;
var type;
var noOfDevice = req.body.noOfDevice;
for (var i = 0; i < noOfDevice; i++) {
var k = i.toString();
macAdd[i] = req.body.macAdd[i];
useWith[i] = req.body.useWith[i];
type[i] = req.body.type[i];
//console.log(req.body.macAdd);
process.deviceManger(macAdd[i], useWith[i], type[i]);
console.log('Device' + i + 'Details Update');
}
function getDeviceCount(sel) {
console.log("No of Device:" + sel.value);
var currCount = sel.value;
var div = document.createElement("div");
for (var i = 0; i < currCount; i++) {
div.setAttribute('id', 'addElements');
div.innerHTML += '<div class="row"><div class="form-row"><div class="form-group col-md-3"><label for="inputCity">Mac Address</label><input type="text" class="form-control" id="macAdd" name="macAdd' + i + '"></div> <div class="form-group col-md-3"><label for="inputState">Type of Device</label> <select id="inputState" class="form-control" name="deviceType' + i + '"> <option selected>Select</option> <option value="Irys Slate">Irys Slate</option> <option value="Irys Sling">Irys Sling</option> <option value="Irys Swing">Irys Swing</option> </select> </div> <div class="form-group col-md-3"> <label for="inputState">Use with</label> <select id="inputState" class="form-control" name="useWith' + i + '"> <option selected>Select</option> <option value="All">All</option> <option value="Nconnect">Nconnect</option> <option value="Tiara">Tiara</option> <option value="Corona">Corona</option> <option value="TiaraMini">TiaraMini</option> <option value="Nconnect+Tiara">Nconnect+Tiara</option> <option value="Nconnect+Corona">Nconnect+Corona</option> <option value="Nconnect+TiaraMini">Nconnect+TiaraMini</option> </select> </div> </div> </div>';
document.getElementById("devices").appendChild(div);
}
